ManufacturerR.K. Instruments & Controls
R.K. Instruments & Controls manufactures and supplies Angled (Bent-Tip) Special Ignition Electrodes — threaded, spark-plug-style igniters with a 90° angled ground/mass arm, used for direct spark ignition in gas engines, CHP (Combined Heat & Power) plants, biogas and natural gas generator sets, and industrial burners. Built to the widely used M14 x 1.25 or M18 x 1.50 threaded mounting format, each unit is manufactured to order with a chromium-silicon stainless-steel center electrode, nickel-chromium ground arm, and low-loss steatite or high-alumina ceramic insulation. Bend angle, overall length, thread size and materials can all be customised on request for gas engine OEMs, CHP operators and burner service applications.
